lo to make and use the laame, reference being had to the accompanying drawings, which iorm a part of thisI apeeifieation.

This invention relates tomeaauring tape reels and has for its ohj'eet a Special form of i5 ronstruetion for the uuwlianism that controls the handle or crank hy whieh the. reel is revolved. It embodies a unitary structure that performs both the 'fonction oi" lati-hing the rrauh arm in position and thrustingr4 the 2o c'rauli arm out `from the aide oi the reel when the lati-h is released.

in the drawinm: -Figure 1, an elevation ot' the inside of the reel, one ot the side walls heilig removed. lfig. 2, .is a Cross sec- Fig. 3, is a rrons Section on the iiue 2&3 oi" "t, ia a side elevation of. the tape reel in plare position for rotatinga the reel.

v'linder having,V a ventral post i whieh is held in piaf-e hy the plate /I. This plate of the shape shown in Fig. i and it has a pair of earn` Ci and 4 which are heut through the. slot -`enfra the end -wall of the drum and "f'orm the heariwts'@Land4 that support the erank arm t3 h v a pintlet"aiiowpivotal movement. 'hese ears 3 aud4 also serve to hold .the plate 2 tothe end wall ot' the drum. .ht the a split It lith; adjaerntthe eide wall ot the lletween the portiona formed hy the is impiuled a wire Spring l0. The f) is held in plare hy the portions 'il lL whieh are. sti-urk out ot' theI metal 'of' the side wall oi' the drum. This spring Iii has: a latch arm i whirh extenda across one aide ot' the end of the drum and heisa aud -ttasteued to ita extreme end, the stud plato drum. split plate 5G passing through a Slot l5 so that the head oi the Stud le lies on the outside ot' the end wall oil the drain; the other arm, which will he hirm'ed the thrust arm it', extends across the apooaite side of the end wall and returns part. way upon itseiii and its end i8 engages Fig. 'L Fig.v

The tape reel or drum A is a closed-emi mes lof the tap and also guides the tape through an opening 19 in the end Wali and hears upon the crank arm (3 when that meinu her 1s lying against the end wall oi' the drinn as Shown in Figs. il and 3. lVhen the crank arm G lies against the end wall of the drum, it is held in that position hy reason ofv the handle Q0 which has a. neck portion and an enlargement or head that are riveted to the handle hy the rivet Q1 and are engaged by the lateh arm 18, whieh springs iii-against the neck portion and prevents the enlarged portion' ot' the handle from passing by the spring without the exercise ot' force to thrust it by.

Referring; te Fig. i, it will he seen that, if the stud i4 is moved to the right in the slot l5, that it will move the latch arm i?) out from engagement with the handleand hence leave the handle free to move outward. linn'udiately the thrustarin ii" Comes into play, the loop portion thereof being under tension, spreads and thrusts the crank arm ont ward with lwinetftoree so that it may he 'readily l:fraaped and the crank arm may he eaused to assume the position in Fig. 4, wherein it may he used to rotate the drum.

The measuring tape 23 is shown attaehe/: to the drum by a loop in Fig. i. A. 'eerveutional form ot' leather-eovered easingl l ia shown in Fig. 4 and this shields the windto properly wind upon the reel. yihe other sidewall ot the tape drum A may he tas tened to the post l by a serew (not shown) that engagea` in the Srrew--tln'eada ot' the post. liroin the. above desrription` it wiil he seen thatmy tape reet is Simple and lrheap to eonstruet and etl'ertively aecomphahea the tunrtious ot latrlungr the handle' to the tape drum when not iu une and tori'- ing the handle out when the latch has heen released.

What I elaim' iaiv l. A tape reel, having; in combination, a eyiindei' upon whieh the .tape winds and having; an end wali provided with a hole, a crank arm for revolving the same pivoted thereto and provided with a handle, the said, handle adapted to protrude through the aaid `hole in the end wall ot' the Cylinder when the crank arm lies against the end wail, a spring' mounted in said cylinder and having an a rar adapted to engage with the head oi: the handle to yielding-ly hold the handle in the cylinder in closed position and a alidstud on one end of the cylinder and attehed to the spring Wire for nioving the spxtlng Wire out of engagement with the handle to release the crank arm, substantially fas described. 2.
